VAPORIZER AND CARBURETER.

Specification of Letters Patent.

Patented Mar. 3, 1914.

Application filed September 3, 1913. Serial No. 788,028.

To all whom it may concern:

Be it known that I, FRANK G. UNDER- woon a citizen of the United States, re

. vaporized as is also water to commingle with the volatilized fuel and air, to produce a thoroughly mixed carbureted air before; the same is introduced into the explosion chambers of an engine.

A further object of the invention is the provision of means adapted to be disposed or incased about a portion of the exhaust manifold of an explosion engine, and con stituting a mixing chamber for the liquid and air, an accelerating fluid in the form 9f water converted into a steam being used 111 conjunction therewith, so that a properly I mixed carbureted air 1s supplied to the explosion chambersof the engine.

A still further object of thepresent invention is the provision of means'whereby the supply of the fuel and water to the mlxing chambermay be regulated to produce a carbureted air of the best proportions;

With the foregoing and other objects in view which will appeal-as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the-drawings: Figure -1 is a diagrammatic view partly in section of the present invention as used in connection With an explosion engine. Fig. 2 is an enlarged detail with an exhaust manifold 2, which extends through the carbureted air mixing cylinder or chamber 3 to the muffler 4.

The present chamber 3 is shown cylindrical and horizontally disposed, but it is evi dent that the same may be connected in any,

manner according tothe installation of the explosion engine and the position of the exhaust manifold, it being the intention of the present invention to' osition the same upon the exhaust manifold of any engine as installed or as presently constructed.

The mixing chamber '3 is provided with the air inlet 5 so that as the carbureted air is drawn into the explosion engine in the usual way through the manifold 14, air will be drawn into the chamber or compartment 3 to be mixed with the volatilized fuel and steam. pipe 6 is led from the liquid fuel reserv01r (not shown), and is provided with the manually controlled valve 7, which permits the proper supply of the fuel through the nipple or nozzle 8 at a point directly above the exhaust manifold within the mixing chamber 3. A pipe 9 is led from a water reservoir (not shown), supplied therethrough valve 10 so that the proper amount is atomized from the nozzle 11 upon the exhaust manifold 2 within the mixing chamber 3.

As the exhaust manifold is heated from the discharged burnt gases from the explosion engine I, the liquid fuel is immediately vaporized while the 'water is converted into steam, thus producing with the air.entering the port 5, a highly explosive mixture for introduction through the port 13 of the extension 12 of the intake manifold 14 of the explosion engine. The extension 12 of the intake manifold is disposed within the mixing chamber 3, so that the same will be heated from the exhaust manifold 2 within such mixing chamber, and thus insure the delivery through the port 13 and the intake manifold 14 of a properly mixed and heated carburetedair charge. By this means all streaks are eliminated from the mixture and a carbureted air charge with the minimum proportion of fuel which will produce the maximum power is delivered into the explo sion chambers of the enginel.

By means of the valves 7 and 10, the control of the liquids to the mixing chamber 3, may be properly proportioned and if so dc-' so that water may be and controlled by the supplies any deficiency sired, a butterfly valve or the like may be disposed in the air inlet pipe or port 5.

By using water, less fuel (oil) is-found necessary as the hydrogen augments the explosive components of the kerosene oil, or any fluid hydrocarbon, while the oxygen that might arise from air not containing of oxygen, or what'is known as Vhat is claimed is zbad air The combination with the exhaust and intake mamfolds of an explosion engine, 01; a

vaporizer and carbureter, including a casing surrounding a portion of the exhaust inanifold and having an air inlet port at its upper portion near intake pipe", mounted within and near the upper portion of the casing, ing a port in its lower wall Within the casing at a point remote from the air port, one end of the pipe being in communication With the the proper amount one end, a carbureted air.

said pipe hav- 1 withinthe easing below the pipe and termlnating directly above and out Y of contact with the exhaust manifold, and a'water direoting nozzle mounted in the upper wall of the casing and parallel with the explosive liquid nozzle, whereby the explosive liquid and Water are directed upon the exhaust manifold within the casing at points between the air inlet port and the port of the intake Plpe' In testimony that Lclann the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
